Of course it would be great, Totoloco. But the problem is, this extension is trying to draw numbers using ansi art (creating shapes with a combination of characters) and this does not help accessibility in any way. If anything, it makes things even harder! There are automated solutions to solve captchas for the blind, but they can't be used for this captcha. This method is quite secure, but inaccessible.

Am I correct in assuming that this extension is trying to be accessible, based on this statement? If so, please tell me how I can make sense of "._. ._.: ;" as someone who is blind and uses a screen reader (http://en.wikipedia.org/wiki/Screen_reader). Imagine hearing, dot underscore dot semicolon dot underscore! :-)
